100th Anniversary of Bohr's Model of the Atom

摘要

One hundred years ago this autumn, the young 27-year-old Danish physicist Niels Bohr published his atomic models. In 1911-1912 he had visited the centers of experimental and theoretical atomic physics: Cambridge (where Thomson, the Nobel Laureate of 1906, had discovered the electron in 1897) and Manchester (where Lord Rutherford, Chemistry Nobel Laureate of 1908 for studies in radioactivity, had discovered the atomic nucleus in 1911). The harvest of Bohr's postdoctoral stay comprised in particular three papers with the comprehensive title "On the Constitution of Atoms and Molecules" published in the Philosophical Magazine in the fall of 1913. The papers became famous as "Bohr's Trilogy". His "investigation of the structure of atoms" earned him the Nobel Prize in 1922 (Figure 1).
